[gradsusr] Valid components of the substitution template for the TIME

[Jeff Duda]

Minella,
I hope someone else can settle the root cause for you, but I have a
suggestion you can use to "brute force" this issue. Use %ch for your
forecast hour string and manually type in the value of each time increment
in the control file using CHSUB. That is,

dset ^./northeast_c3s_ecmwf_20010101_t00z_f%f3_m000_tp.bin
options template
CHSUB 1 1 24
CHSUB 2 2 48
CHSUB 3 3 72
...
...
...
CHSUB 214 214 5136
CHSUB 215 215 5160
undef   9999.0
title c3s data
xdef 320 linear 310.0000000 0.05
ydef 440 linear -22.0000000 0.05
zdef 1 linear 1 1
tdef 5160 linear 00z01Jan2001 24hr
vars 1
tp 0 99 Total precipitation [m]
endvars

That is clearly very intensive work, so you would probably instead just
write a simple script in whatever language (FORTRAN, Python, Linux shell
etc.) to write out those lines for you and re-construct the control file.
That should at least serve as a temporary workaround.

Best of luck!
